What else can I help you with?
Can calcium oxide be used to neutralise water polluted with acid rain?
No, you need Calcium Carbonate not Calcium Oxide to neutralize the acid.
Is calcium nitrate soluble in water?
Yes, calcium nitrate is highly soluble in water. It readily dissociates into calcium ions and nitrate ions when dissolved in water.
Does calcium nitrate dissociate in water?
Yes, calcium nitrate does dissociate in water to form calcium ions (Ca²⁺) and nitrate ions (NO₃⁻). This dissociation process allows the ions to be mobile in solution, making calcium nitrate a soluble compound.
Will calcium nitrate lower the pH in water?
No, calcium nitrate will not lower the pH in water. In fact, it may slightly increase the pH because calcium nitrate is a neutral salt that can act as a buffer in water.
What happens when mixing calcium nitrate in water compound?
When calcium nitrate is mixed in water, it dissociates into its ions: calcium (Ca2+) and nitrate (NO3-). These ions remain in solution and are free to interact with other substances present in the solution. The solution will also undergo an endothermic process as the dissolution of calcium nitrate in water absorbs heat from the surroundings.
What makes water with calcium oxide and calcium nitrate?
The reaction of calcium oxide and calcium nitrate dissolved in water forms calcium hydroxide and calcium nitrate solution. Calcium hydroxide is a white precipitate that forms when the two substances react together.
How soluble is calcium nitrate in water?
The solubility of calcium nitrate in water at 20 0C is very high: 1 212 g/L.
What two chemicals together create calcium nitrate?
Calcium nitrate is typically created by combining nitric acid with calcium carbonate or calcium hydroxide. This reaction results in the formation of calcium nitrate, water, and carbon dioxide.
Why does calcium nitrate have a high conductivity?
Calcium nitrate is a salt that dissociates into calcium and nitrate ions when dissolved in water. These ions are free to move and carry electric charge, leading to high conductivity. Additionally, calcium nitrate is highly soluble in water, which further enhances its conductivity.
What compound is made when nitric acid is neutralised?
A Nitrate salt depending on what was used to neutralise the acid. E.g. If you used copper to neutralise the nitric acid then copper nitrate would be produced.
Does calcium nitrate and water make a precipitate?
no
Can you obtain pure calcium nitrate crystals by evaporating the solutions to dryness?
Yes, you can obtain pure calcium nitrate crystals by evaporating the solution to dryness. As the water evaporates, calcium nitrate will start to crystallize out of the solution. To ensure purity, it is important to start with a pure calcium nitrate solution and use distilled water for evaporation.
